Abstract: Methods, systems, and devices are described for techniques for downlink (DL) scheduling and uplink (UL) scheduling in a shared radio frequency (RF) spectrum band. In some aspects, a wireless communication device may receive an UL data transmission grant associated with a channel of shared RF spectrum band. The wireless communication device may perform a channel readiness procedure associated with the channel. The wireless communication device may also transmit channel readiness information based at least in part on the channel readiness procedure to a base station. The channel readiness information may be transmitted via an uplink channel of a licensed RF spectrum band different from the shared RF band. In other aspects, a base station may schedule a data transmission on one or more channels of a shared RF spectrum band. The base station may transmit a data transmission grant for the scheduled data transmission to a wireless communication device.

Abstract: Systems and methods are disclosed that may determine phase offsets in wireless devices. In accordance with some embodiments, a phase of a local oscillator signal associated with transmission of data from a wireless device may be measured by generating a reference signal having a frequency that is a selected integer value times a frequency of a baseband clock signal, generating the local oscillator (LO) signal to have a frequency substantially equal to a carrier frequency of the data transmission, and mixing the reference signal and the LO signal to generate a mixed signal indicative of the phase of the LO signal.

Abstract: A peak angular velocity time, at which a peak value of an angular velocity around a vertical axis of a vehicle occurs while the vehicle is turning, may be determined. A peak lateral acceleration time, at which a peak value of linear acceleration along a lateral axis occurs while the vehicle is turning, also may be determined. The peak angular velocity time and the peak lateral acceleration time may be determined according to input from inertial sensors of a mobile device. The lateral axis may be perpendicular to the vertical axis and perpendicular to a longitudinal axis of the vehicle. A first time difference between the peak angular velocity time and the peak lateral acceleration time may be calculated. Based at least in part on the time difference, it may be determined whether the mobile device is in a front area of the vehicle.

Abstract: Various methods and apparatus are directed to collision detection and/or avoidance regarding peer to peer connection identifiers. A wireless communications device broadcasts a signal indicating its acquired connection identifier in one of two alternative blocks. A base station monitors peer to peer signaling in its coverage area and tracks the usage of peer to peer connection identifiers by pairs of devices. The base station detects when multiple pairs of devices are using the same peer to peer connection identifier. The base station provides assistance to the peer to peer network to avoid a collision or facilitate rapid collision detection by the peer to peer devices. In one approach the base station sends an instruction for a connection to switch its connection identifier. In another approach the base station sends a connection a message to bias its selection as to which of the two alternative blocks to use for transmission.
